-## Description
-
-Our mission is to provide **safe** and **performant** wrappers for UEFI
-interfaces, and allow developers to write idiomatic Rust code.
-
-This repository provides various crates:
-
-- `uefi-raw`: Raw Rust UEFI bindings for basic structures and functions.
-- `uefi`: High-level wrapper around various low-level UEFI APIs. \
-  Offers various optional features for typical Rust convenience, such as a
-  Logger and an Allocator. (_This is what you are usually looking for!_)
-- `uefi-macros`: Helper macros. Used by `uefi`.
-
-
-You can use the abstractions for example to:
-
-- create OS-specific loaders and leverage UEFI boot service
-- access UEFI runtime services from an OS

 ## Developer Guide
 
-### Project structure
-
-This project contains multiple sub-crates:
+### Repository Structure
 
-- `uefi`: defines the standard UEFI tables / interfaces.
-  The objective is to stay unopinionated and safely wrap most interfaces.
-  Additional opinionated features (such as a Logger) are feature-gated.
-
-- `uefi-macros`: procedural macros that are used to derive some traits
-  in `uefi`.
-
-- `uefi-raw`: raw types that closely match the definitions in the UEFI
-  Specification. Safe wrappers for these types are provided by the `uefi`
-  crate. The raw types are suitable for implementing UEFI firmware.
-
-- `uefi-std-example`: Example UEFI app but as Rust standard binary.
-
-- `uefi-test-runner`: a UEFI application that runs unit / integration tests.
+This repository provides various crates:

+- [`uefi`](/uefi/README.md): High-level wrapper around various low-level UEFI
+  APIs. This crate makes it easy to develop Rust software that leverages safe,
+  convenient, and performant abstractions for UEFI functionality.
+  This is the **main contribution** of this project.
+- [`uefi-raw`](/uefi-raw/README.md): Raw ABI-compatible types that closely
+  match the definitions in the UEFI Specification. They are suitable for
+  implementing UEFI firmware or creating interfaces to it.
+- [`uefi-macros`](/uefi-macros/README.md): Helper macros used by `uefi`.
+- [`uefi-test-runner`](/uefi-test-runner/README.md): A UEFI application that
+  runs our integration tests.
+- [`uefi-std-example`](/uefi-std-example/README.md): Example UEFI app but as
+  Rust standard binary.
